advanced circuit design to provide ultra-low active current.
This is ideal for providing More Battery Life™ (MoBL
portable applications such as cellular telephones. The device
also has an automatic power-down feature that significantly
reduces power consumption by 90% when addresses are not
toggling. The device can be put into standby mode reducing
power consumption by more than 99% when deselected (CE
HIGH). The input/output pins (I/O
in a high-impedance state when: deselected (CE HIGH),
outputs are disabled (OE HIGH), both Byte High Enable and
Byte Low Enable are disabled (BHE, BLE HIGH) or during a
write operation (CE LOW and WE LOW).
Writing to the device is accomplished by taking Chip Enable
(CE) and Write Enable (WE) inputs LOW. If Byte Low Enable
(BLE) is LOW, then data from I/O pins (I/O
written into the location specified on the address pins (A
through A
from I/O pins (I/O
specified on the address pins (A
Reading from the device is accomplished by taking Chip
Enable (CE) and Output Enable (OE) LOW while forcing the
Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW,
then data from the memory location specified by the address
pins will appear on I/O
LOW, then data from memory will appear on I/O
